Explanation:

1. It is difficult to recycle polyvinyl chloride into plastic bags because it is a very hard plastic. Polyvinyl chloride is a widely used plastic because it is durable and stable with an average life span of 30 years.

2. HDPE is a good material for boats because of its high tensile strength and low density. HDPE stands for High-density polyethylene. It is lightweight and impervious to damage.

3. HDPE. This is because it is unaffected by alkaline solution. It's corrosive nature gives it resistance to damage.

4. HDPE is used in making plastic lumber.

It is also used in producing geomembrane.

5. To separate the mixture of PETE and HDPE, you would need to employ the flotation method of separating mixtures. Mixtures are separated based on their hydrophobic and hydrophilic abilities. The mixtures are placed in a condensed tube, and stirred. The substance with a lighter weight stays at the top while the heavier one stays below. They are then removed separately.

Valeric acid, HC5H9O2 (Ka = 1.5 ✕ 10−5), is used in the manufacture of magnesium valerate, a nerve-calming agent. What is the hy

Studentka2010 [4]

Answer:

$[H^+]=0.00332M$

Explanation:

Hello,

In this case, considering the dissociation of valeric acid as:

$HC_5H_9O_2 \rightleftharpoons C_5H_9O_2 ^-+H^+$

Its corresponding law of mass action is:

$Ka=\frac{[H^+][C_5H_9O_2^-]}{[HC_5H_9O_2]}$

Now, by means of the change $x$ due to dissociation, it becomes:

$Ka=\frac{(x)(x)}{0.737-x}=1.5x10^{-5}$

Solving for $x$ we obtain:

$x=0.00332M$

Thus, since the concentration of hydronium equals $x$ , the answer is:

$[H^+]=x=0.00332M$

Best regards.

Methane gas and chlorine gas react to form hydrogen chloride gas and carbon tetrachloride gas. What volume of carbon tetrachlori

mario62 [17]

Answer:

0.55mL of carbon tetrachloride

Explanation:

CH4(g) + 2Cl2(g) -------> CCl4(g) + 2H2(g)

From the balanced reaction equation

44800mL of chlorine produces 22400 ml of carbon tetrachloride

If 1.1mL of chlorine were consumed, volume of carbon tetrachloride= 1.1×22400/44800

=0.55mL of carbon tetrachloride

Note: 1 mole of a gas occupies 22.4L volume or 22400mL

What happens when hydrogen reacts with nitrogen at necessary conditions.

Orlov [11]

Answer:

When hydrogen gas combines with nitrogen to form Ammonia the following chemical reaction will take place. Our equilibrium reaction will be N2(g) + 3H2(g) ⇔ 2NH3(g) + Heat. In this case, Hydrogen and nitrogen react together to form ammonia.
